This was my first order with Staples and am imminently satisfied with both the products that I ordered and the timing of the delivery of the items. My printer seems to heat envelopes so much so that the ones I was using from that big ole' Mart around the corner just were sealing shut whenever me move them through the printer. So I had my assistant set up a Staples account since my prior firm had an account with Staples. My assistant uses the envelopes and she says they are working outstandingly.
